Jun 7, 2015 at 18:03 comment added Cheers and hth. - Alf @Cicero: Some specific concrete proposals for dark matter are falsifiable. I'm no expert, but I find e.g. Jay Wacker (a physicist from Stanford) saying this on Quora: «The ultimate issue is that at this point, dark matter's non-gravitaitonal interactions may be arbitrarily weak. It doesn't make it non-scientific, it just means that we may be forever ignorant of the details of the non-gravitational interactions of dark matter.». The phrase «forever ignorant» is, as I see it, the same as «not falsifiable». And I think, if that's not so, then it would be such glad tidings that I would have heard
Jun 7, 2015 at 16:30 comment added Cicero @Cheersandhth.-Alf With respect to dark matter, it is falsifiable. All current developed theories that avoid dark matter by not being metric theories like General relativity cannot account for galaxy clusters. Those which account for Galaxy clusters (general relativity and similar metric theories) need dark matter to explain other galactic phenomenon. In short, there is no alternative to the dark matter model which accounts for as much phenomenon. When such a model is developed, then people will gladly abandon dark matter. Till then, the most successful model will reign.
Jun 6, 2015 at 10:46 comment added Cheers and hth. - Alf It's worth noting first, that science is divided into hard and soft sciences (with even finer grades), and secondly, that currently there's widespread acceptance of various math-based hypotheses as science in spite of not being falsifiable and in spite of total lack of experimental evidence or even the possibility of such. Dark matter comes to mind. Everywhere you'll find alleged evidence of dark matter, when it's only evidence of the phenomenon that dark matter was invented to pseudo explain. Evidence of problem = evidence of interpretation; this is now called scientific. We're in bad shape.
